SIGNAL FOR vEHaoLEs.

Specification of Letters Patent. Application filed November 15. 1904. Serial No. 232,872.

To all whom' it may concern:

Be it known that I, ARTHUR RosING, a subject ofthe King of England, residing at Paris, France, have invented Vnew and useful' Improvements in or Relating to Signals Jfor Vehicles, of which the following is a s eciiication.

his inventionfrelates te a signal system for motor-cars, tram-cars, or other vehicles in which 'the application of centrifugal force transmitted byone of the wheels is employed yto .exhibit in a window or trame suitablyr arranged at the back of the car a suitable slgnal consisting, for instance, of the words Stop', Slacken/ Back in orderto notify drivers of vehicles at Vthe back that they must stop,

slowdown, or' back in order toavoid accidents, so that the driver is no longer required to make the usual signals.

In the accompanyingdrawings, by-way of example, Figure 1 shows a plan view, partly in` section, of part of the back of a vehicle,- showing an application of the system. Fig.' 4

2 is a iront -view of the signal-board. Fig. 3

. is a section on line 3 3 of Fig. 2. Figs. 4 and 5 are detailviews-oi parts ofthe apparatus.

To the back of the vehicle-is secured a support 6, terminating in a sleeve 7, in which can freely turn the sleeve 8 oja ball-governor 9,

the central shaftlO of which can freelv move in the inner sleeve 8 and 1s attached at itsend,

by means of a ball-joint 11 to a co1d.12,pass. ing over a guide-pulley 13 and preferably mounted in the interior of a tube 14. The other end of this cord is attached lto one end of a pivoted lever 15, the other end of which l is provided with a slot with which engages a stud 16, secured to the back of a board 17, 'which can freely move vertically along a slide 18 of a frame orcasing 19, secured to the back of `the can The back of this frame is pro.-v

vvided with a window or opening 20, below which another vertically-movable board 21 is guided.

On thesleeve 7 is concentrically mounted `a ratchet-wheel`22, Fig. 5, with the teeth'ofv which engages a pawl 23, pivoted to an arm 24, loosely mounted in a grooye in the sleeve 7, to which arm is attachegi'fthe end of a cord` 25, guided between pulleys-2626, mountedon a vbracket or support 27, Asecured to the sleevel 7. This bracket or support is pro-l vided at each of its ends with a tappet 28,

serving to-limit the movement of the arm 24.'

The cord 25 passes oyer a guide-pulley 29,

preferably mounted inthe interior of the HERMANN.

tube 14, over asecond guide-pulley 30 and isattached with its end to one end of a pivoted lever 31, the other end of which carries the lower board' 21, as shown in Fig. 2.

In the interior of the ratchet-wheel 22'is a circular groove32, in which is `placed a-curved ernor 9, which is -not working', are brought close together-and' no traction is exercised by the governor on the cord 12. .The board 17 is therefore in its lowest position behind the lowest board, and the word Stop l with which it is provided appears at thewindow '20. As soon as the car starts the pulley 35 transmits to the pulley34, to thesleeve 8,

andto the balls of the governor a rotary mo-A tion', the result of which is that the balls of thelatter move apart and traction is exercised onthe cord 12, which swin s the lever 15, and the board 17 rises until t e carhaving reached its normal speed the board-17 lis completely raised and no indication appears inthe window 20. If the speed of the car begins to decrease, the balls of the governor 9 a proach nearer to 'each other', the cord 12 is sackened, and the board 17'descends by bringing the word Slacken in,

gravity,I front of 'the window 20. In the. event` of a complete stop the balls come still nearer together, and the board 17 sinks sufficiently low for the word fStop to appearat the window 20.

' If the car is moving backward, the pulley 35 traiismitsto the pulley 34 a rotary movement 'in the opposite direction, and then the ratchet 22 acts onl thepawl 23 and swings the arm A24, which exercises a pull on the cord 25, guided between the rollers 26. This traction results in the lever 31 being turned, raising the board 21 so that the Word Back appears at the 'window -or opening 20. 'If the backingk continues, the sleeve 8 rotates while exercising friction on the spring 33 without oarryin the ratchet 22, but in-such manner that t e friction is suiicient to hold thearm 24 inclined and the board 21 raised. It, therefore, the car slackens its speed, the word Slaoken appears at the ratenreduuiy 31,1906.

1 Ward, the Word Window v20. If the. car stops, the Word Stop" appears there, and if it travels back- Back will appear. In any case the drivers of vehicles vbehind are thus warned Without the driver of the car carrying the apparatus being obliged to make any signal or to trouble about vehicles behind It is important that inspite of the vibra tions of the car the board 17 should remain stationary. To that end a spring 37 is Wound round the pin 38 of the lever 15, which. engages with one of itsends in a hole .in the bottom of the frame 19, which forms a support for it. One of the ends of this spring 37 enters a hole in the frame 19, and the other end engages in a hole in the lever 15, as shown in Big. 4, sothat owing to the interposition of the spring between the frame and the lever the vibrations of the latter due to the vibrations of the car are suppressed or taken up.

At night-time the signals Will be suitably` illuminated, so that they may be visible.

l/Vhat Iclaim as my invention, and desire to secure by Letters Patent, is,h

1'. In a signal for vehicles, the combination with a centrifugal governor of means for operatin the said governor from one of the Wheels o? the vehicle, of a frame arranged at the back ofthe car and provided with a Window or opening, .e movable board in said frame carrying two Words a second. board also movable in the frame and carrying another Word a lever attached. to tile i'irst board and connected. by a cord to the sleeve of the governor,. another lever operating the second board, a cord attached to this second, lever, an arm attached to the cord and a ratclfctgear mounted rictionallyf on. the sleeve of the governor, substantially as described.

2. ln a signal for vehicles, the conibination with a ccntriln al governor, of a sleeve carrying the arins lor the balls of the gnvernor, a grooved pulley mounted on the said sleeve, a rroovcd pulley attached to one of the Wheels of the vehicle, a frictioi'mllymounted paWl-gear on said sleeve an arm fixed on the pand-gear, an indicator-board movable in the indicator-frame and mea-ns for transmitting the movement of the said arm to the said indicator-board, .substantially as described.

In Witness whereof l have hereunto my name, this 19th day of October, 1904., in the presence ol2 two subscribing witness ARTHUR HERMAN N ROSING. v Witnesses:
